The SpermVital semen produced as expected significantly better results than the regular semen.
Increase up to 38% in conception rate
The conception rate increased on average by 25%, from 33.5% with regular semen to 41.9% with SpermVital semen. The difference in conception rate increased with the number of inseminations needed. The difference in conception rate was 38% between SpermVital semen and regular semen on cows needing more than 3 inseminations. These incredible results show that cows that return to heat increase their conception rate greatly by utilizing the SpermVital technology.
These results also correspond well with the results that German and Dutch dairy farmers are experiencing with the use of the SpermVital technology, even though they are using SpermVital NRF semen on Holstein cows, and therefore are seeing an additional effect from the Norwegian Red.
2076 doses of semen were used in this blinded field trial, where half of the inseminations were made with Holstein SpermVital semen and half with regular Holstein semen. The Holstein cows were inseminated at normal time, which is not the optimal time for insemination to achieve full effect from the SpermVital technology since it will not capture the ones with early ovulations. Normally you will inseminate a little early when you are using the SpermVital technology to achieve all the benefits the technology has to offer.
